3 PREAMBLE The standard sequence of Australian competitions runs across two calendar years. The State Finals held Sept/Oct/Nov in one year will feed to the National Final in February/March of the following year. This encompasses a complete season, for which the rules SHOULD remain constant. REA reserves the right to update / revise the rules if deemed appropriate. It should be noted that there have been some rule changes/clarifications made between the 2012/13 and 2013/14 season Australian rules. These changes are highlighted in blue coloured text. Changes made midseason will appear in green coloured text. Please read them carefully in conjunction with the 2013/2014 General Information Booklet. Note: For teams aspiring to represent at the World Championship, the world rules are different to the Australian. Competition Classes Teams will be classified as Professional Senior, Professional Junior, Development Class or Cadet Class. This document covers all classes and some rules are not relevant to all. Specific clauses addressing Professional Class Teams only are identified by [PC Only]. Specific clauses addressing Development Class Teams only are identified by [DC Only]. Specific clauses addressing Cadet Class Teams only are identified by [CC Only]. Language Used The language of the rules is tiered. Those clauses expressed as MUST are mandatory and failure to comply will attract objective penalties - points and/or racing and/or in the extreme, disqualification. Those expressed as SHOULD or MAY reflect some level of discretion and choice. Some clauses will be satisfied through team registration processes or declarations signed as complied with as part of the Challenge Agreement whilst others will be tested through a variety of objective and subjective judging. Specific clauses; invoking scrutineering point penalties, are identified by [Point Penalty]. invoking racing penalties, are identified by or [Ballast Penalty]. o o Time Penalty = 1/10 second applied to every run/lap for every rule or regulation violated up to a maximum of.5 second. Ballast Penalty = 2 grams applied for every gram underweight or part there-of (rounded up) and applied to each car submitted. E.g. 2.1gms underweight equals 3gms x 2, totalling 6gms of ballast. State & National Final Judging State and National final judging will include all categories detailed in the marking criteria which can be downloaded from the REA website at: Note: Some school and regional events MAY not judge all criteria so check with the relevant coordinator. School and Regional events are NOT managed by REA. Note: The Cadet Class will not proceed beyond the state final level of competition in the 2013/2014 season. However State Champions in this class will be invited to display their projects at the 2014 National Final. Overall winners of State and National Finals will be determined by combining point scores from all categories. Other prizes will be determined on separate or a combination of category totals. IN ALL COMPETITIONS, THE CHAIR OF JUDGES DECISION IS FINAL. All supplementary information is available via the REA web site, Any questions concerning rules MUST be ed to contact@rea.org.au. 3 P a g e

NOSE CONE RULES The nose cone is defined as any part of the car forward of the centre line of the front axle that isn t defined as being an aerofoil, tether line guide or tether line support. a. Professional Class and Development Class Teams MAY manufacture the nose cone or parts thereof from separate, non-metallic materials. b. Alternative non-metallic materials forming the nose cone MUST NOT be present behind the centreline of the front axle. Advice Disqualification 10 P a g e

11 6. AEROFOIL RULES An aerofoil is an aerodynamic device defined geometrically by its span, chord and thickness. For a horizontally oriented aerofoil, the top and bottom surfaces of dimension span x chord could be pressure or suction surfaces depending on the angle of attack and/or the cross sectional shape. a. The whole of the front aerofoil when viewed from the side MUST be in front of the centre line of the front axle. b. The front aerofoil MUST be connected only to the nosecone. c.

Both aerofoils top surfaces MUST be 100% visible from the car top view. h. Professional Class and Development Class Teams MAY manufacture the front aerofoil Advice 11 P a g e

12 and any supporting structure connecting it to the nose cone from separate, nonmetallic materials. i. Professional Class Teams MAY manufacture the rear aerofoil and any supporting structure from separate, non-metallic materials. j. If Professional Class Teams manufacture the rear aerofoil and any supporting structure from separate, non-metallic materials, these materials MUST be completely contained within the volume created by the vertical projection of the plan view of the rear aerofoil including the natural connection between aerofoil segments where the aerofoil is split by the body. Disqualification Advice Disqualification [PC Only] [PC Only] k. Development Teams MUST manufacture the rear aerofoil and any supporting structure from balsa. l. The span of a front aerofoil: made from balsa MUST be a minimum of 34mm and a maximum of 65mm, or made from an alternative material MUST be a minimum of 40mm and a maximum of 65mm. m. The chord of a front aerofoil MUST be a minimum of 15mm and a maximum of 25mm. n. The thickness of a front aerofoil: made from balsa, MUST be a minimum of 3.5mm and a maximum of 12mm; or made from an alternative material, MUST be a minimum of 1.5mm and a maximum of 12mm. o. The span of a rear aerofoil: made from balsa, MUST be a minimum of 34mm and a maximum of 65mm, or made from an alternative material, MUST be a minimum of 40mm and a maximum of 65mm. [DC Only] p. The chord of a rear aerofoil MUST be a minimum of 15mm and a maximum of 25mm. q. The thickness of a rear aerofoil: 12 P a g e

13 made from balsa, MUST be a minimum of 3.5mm and a maximum of 12mm, or made from an alternative material, MUST be a minimum of 1.5mm and a maximum of 12mm. In measuring span, the measurement is made parallel to the track surface, on the top or bottom surface of the aerofoil (in the y direction), whichever produces the shortest dimension. Intersecting the aerofoil with other car parts including the body, nose cone or supporting structure reduces the effective span to the sum of the clear airspace envelope segments. The aerofoil chord min/max dimensions MUST be satisfied across the full dimensions that define the aerofoil span. The chord is measured in the x direction. Supporting structures are not included in the measurement. The aerofoil thickness min/max dimensions MUST be satisfied across the full dimensions that define the aerofoil span and chord. The thickness is measured in the z direction. Supporting structures are not included in the measurement. Note: An undersized span will lead to an undersized chord and thickness. An undersized chord will lead to an undersized thickness. 7. WHEEL RULES a. All cars MUST have 4 cylindrical wheels, two at the front and two at the rear. b. All 4 wheels MUST touch the racing surface at the same time across the full contact width of the wheel (zero tolerance). That is, there MUST be no camber. (Tested using a strip of 80gsm paper on a flat surface.) c. Wheel dimensions MUST be consistent in diameter and circumference across the contact width of the wheel (i.e., tyre tread is not allowed). d. Development and Cadet Class Teams MUST use any combination of four (4) unmodified REA standard wheels. No other parts can be added to the wheels. e. Professional Class Teams MAY use any combination of four (4) unmodified REA standard wheels. f. Professional Class Teams MAY manufacture their own wheels and the wheel materials are unrestricted. (NOTE: modified REA Standard Wheels are classified team manufactured.) g. The front wheel diameter for team manufactured wheels as measured to the extreme outer edges of each wheel MUST be a minimum of 26mm and a maximum of 34mm. h. The rear wheel diameter for team manufactured wheels as measured to the extreme outer edges of each wheel MUST be a minimum of 26mm and a maximum of 34mm. i. The front wheel track contact width for team manufactured wheels as measured between the extreme outer edges along the contiguous contact line of each wheel MUST be a minimum of 15mm and a maximum of 19mm.

[DC & CC Only] [DC Only] [CC Only] [2 Point Penalty [DC & CC Only] Advice [PC Only] 9. TETHER LINE GUIDE RULES The tether line and guides represent a safety feature in running cars on the track. If using REA standard tether line guides, they are designed to work within the 6mm x 6mm tether line slot feature on the standard balsa blank. Therefore it is recommended that this slot remain intact in way of the guide. a. Each car MUST have 2 (essentially circular) tether line guides firmly secured toward the front and rear of the car, located on the underside along the car body centre line. The track tether line passes through these two tether line guides. An adhesive MAY be used to help secure the tether line guides. b. The longitudinal separation of the tether line guides as measured between the outside edges of the guides MUST be a minimum of 120mm and a maximum of 190mm. c. The inside diameter of the tether line guide (referring to the size of the hole) MUST be a minimum of 3.5mm and a maximum of 5mm. d. The track clearance of each tether line guide MUST be a minimum of 1 mm. This is considered a safety issue. Cars MAY be prohibited from racing if unresolved. e. The tether line guides MUST be closed to prevent the tether line from coming out of the tether line guide. This is considered a safety issue. Cars MAY be prohibited from racing if unresolved. f. Adequate strength and fixing of the tether line guides MUST be considered a safety issue and cars with unsafe arrangements will be prohibited from racing if unresolved. Prohibited from Racing g. Tether guide arrangements with sharp edges WILL be prevented from racing. Prohibited from Racing h. Tether line guides and their supports MUST NOT perform any other structural function. Prohibited from Racing i. Cadet Class Teams MUST use the REA supplied Tether Line Guides. 14 P a g e

15 CC Only j. Cadet Class Teams MUST place Tether Line Guides within the 6mm x 6mm tether slot feature on the standard balsa blank. CC Only 10. POWER PLANT PROVISION RULES REA will provide CO 2 cartridges for the State and National Finals. All cartridges will be weighed and sorted before racing starts to be within a 0.25 gram (National) and 0.5 gram (State) weight range for each class of competition. NOTE: Extreme violations of Section 10 rules (rules 10a 10g) could lead to cars being prohibited from racing due to safety concerns or starting pod incompatibility resulting in zero pints for racing. a. The cartridges provide the car propulsion and all cars MUST interface directly with the standard track starting pod mechanism without the use of additional launch equipment. Prohibited from Racing b. The CO 2 cartridge chamber diameter MUST be 19mm. c. The depth of the CO 2 cartridge chamber, measured as continuous material, MUST be a minimum of 50mm and a maximum of 60mm, the base/bottom of which MUST be square to the hole axis. The chamber can be considered a cavity and MAY be formed by balsa and legal rear aerofoil support structure. d. The vertical height of the lowest point of the CO 2 cartridge chamber above the race surface MUST be a minimum of 22.5mm and a maximum of 30mm. e. The wall thickness around the CO 2 cartridge chamber MUST be a minimum of 3.5mm. Provision of this thickness and the car s structural integrity is a safety issue. Inadequate thickness or strength MUST prevent cars from racing on the track. The decision to prohibit a car from racing will be at the discretion of the Chief Scrutineer. f. Paint and other foreign materials MUST NOT be present inside the CO 2 cartridge chamber. g. The cartridge MUST be able to be inserted and withdrawn without removal and replacement of car parts. Prohibited from Racing 15 P a g e

16 11. RACE REGULATIONS The official length of the race track, from start to finish, is 20 metres. The design of the car SHOULD be undertaken with an understanding of the car s journey on the track. The most damaging loads are imparted to the car during the retardation phase after the car crosses the finish line. Cars are typically retarded by running into a buffer comprised of towels. This can be as much as a -20g collision. To avoid engineering deficiency penalties, cars are to be robust enough to withstand this loading as part of the defined use and operational cycle. Standard track environments provide a buffer of towels but during racing, teams are permitted to provide their own retardation environment. Such an environment MUST be approved by a Race Marshal and shall not be attached to the track and it shall be restricted to be fully within their lane. Retardation systems must be in place when the track marshal is ready to launch the cars. No further time delays will be allowed. A Race Marshal will stage the car on the track but teams are permitted to make any adjustments approved by the Race Marshal after the car has been staged, including the use of positioning blocks to align the car in the centre of the lane, however these MUST be removed prior to launch. Teams MUST NOT use devices which interface with the starting mechanism and teams are not permitted to attach signage or other materials to the track or timing system. All cars will be checked for safety, in particular that the tether line guides are secure. If the Judges have any safety concerns, teams can opt to submit their spare car, no less than 15mins before the racing program begins. This substitution will incur a penalty as outlined in Section 12 Car Repair Regulations. Unresolved safety concerns WILL prohibit cars from racing on the track and WILL result in zero points being awarded for ineligible racing events. CO 2 canisters MUST be inserted so that they are situated firmly against the base of the cartridge chamber. Refer to Rule 10c. At REA managed state and national final events two modes of racing WILL be conducted: Automatic Launch Racing, and Reaction Launch Racing (Manual/Driver Launch Mode). At REA managed state and national final events the following race MAY also be conducted: Knock-out Reaction Launch Racing (Manual/Driver Launch Mode) Automatic Launch Racing will be conducted over the course of the competition as per the judging schedule. Team members need to be at the race track during their scheduled race times. Each car will be raced at least twice in each lane of the race track. Reaction Launch Racing will be conducted during the competition as per the judging schedule. All team members need to be at the race track during their schedule time. Drivers will not be allowed to practice during the official race time. Each car will be raced twice in each lane. At the conclusion of Reaction Time Racing, all teams will be ranked using their fastest total time (gross time), to determine each team s Knock-Out Racing seeded position or to directly allocate in a virtual way the Knock-out Racing points. Knock-out Competition Racing MAY be conducted during the Competition as per the judging schedule. Rankings from the Best Gross Lap results of Reaction Launch Racing will determine where teams start in the seeded knock-out rounds. All team members need to be at the race track during their scheduled race times. Each car will be raced (manual/driver launch mode) ONCE in each lane. The single fastest total time (gross time) posted from these 2 races (reaction time PLUS actual car start line to finish line time) will determine the winner for that knock-out heat and that team will advance to the next knock-out round. 16 P a g e

17 12. CAR REPAIR REGULATIONS Car Servicing At the National Final and most State events, Professional and Development Class teams will be allocated time to perform penalty free maintenance on cars in the official car service area. This will be allowed to occur only between automatic launch and reaction launch racing as per the judging schedule. Cadet Class teams will NOT be permitted penalty free maintenance. Car Repair/Substitution If an entry becomes damaged during racing and the damage is determined by the officials to relate to engineering deficiencies, the car MAY be repaired or an identical back-up car used. If a team s back-up car is lighter than their primary race car, it will be ballasted to match race car weight. Any repair or change of car (for any reason) during racing will result in the following point penalties: Professional & Development Class Teams: o Grand Prix Racing: 10 points for any substitution/first breakage, then 5 points for each subsequent breakage o Knockout Racing: 4 points for any substitution/first breakage, then 2 points for each subsequent breakage Cadet Class Teams: o Grand Prix Racing: 3 points for first breakage, then 2 points for each subsequent breakage Penalties are applied against total points awarded for that race event category. Failure to provide a race car (primary or back up) restored to its original design configuration will result in a disqualification from any further racing. If the officials determine the damage is not related to engineering deficiencies, repairs or replacement with an identical back-up car will be allowed without penalty. Damage incurred during a race, before the car crosses the finish line, (e.g. wheel, wing, tether line guide or any other part of the car product separating) will result in a DNF race result. All damage issues and related decisions are to be decided by the race track officials and scrutineers and referred to the Chair of Judges if necessary. 13. MARKING CRITERIA & SCORECARDS The 2013/2014 State & National Final Marking Criteria and Score Cards can be downloaded via RACING General Teams MAY run their car in both the automatic launch and reaction launch (manual launch) sessions of the competition. Both modes of launch deliver a net run time of the car over 20 metres. The net lap times recorded are a practical indicator of the car performance on the track. Cars deemed unsafe or ineligible to race by Scrutineers will be classified as Did Not Start (DNS) in racing events. Damage incurred during a run, before the car crosses the finish line, (e.g. wheel, wing, tether line guide or any other part of the car product separating) will result in a Did Not Finish (DNF) race result. The fastest net run/lap time WILL determine the winner of the Fastest Lap Award and MAY qualify to set a new state or national record. 17 P a g e

18 Introducing a driver s reaction in reaction launch adds to the sport. Reaction launch run times are a summation of the launch reaction of the driver and the car run time on the track. The normal track timing system allows both components to be recorded. In the event of a reaction launch False Start (FS), the car will subsequently be run using automatic launch to record a net lap time but a reaction launch run FS will also be recorded. Under-weight cars will have ballast added for all runs. Time penalties will apply as a result of specific rule violations (applied to every run/lap) for all forms of racing. Point penalties will apply as a result of the need for car repair or substitution during racing and will accrue if multiple repairs/substitutions are required. Professional & Development Classes Typically four (4) runs are conducted in each launch mode with two (2) runs in each lane. Based on each team s best reaction launch run, teams will be ranked for seeding in the knock-out reaction launch racing. Teams not recording a Reaction Launch run time (i.e. four False Starts) will be excluded from Knock-out racing and associated marks. Cadet Class For the Cadet Class, four only reaction launch runs will be conducted, two in each lane. Should Cadet Class students or teams not attend race events in person, the car will be run in automatic launch mode. Knock-out Racing will not be conducted for Cadet Class teams. 1. GRAND PRIX RACE Due to variability in track conditions, the Grand Prix Race marks and the Fastest Car Award will be awarded based on multiple runs, similar to a multiple lap race. The Race Time will be the sum of the recorded net lap times where the single fastest and slowest laps recorded are excluded. One lap DNF can be considered the slowest lap and excluded. A second lap DNF will lead to the car being deemed as failing to complete the race. Teams will be awarded points that match the performance of their car when compared to the fastest car in the competition. The scaling system uses the following formula to calculate points: Professional & Development Classes Regional Final Race Points = 75 + (120 / (Fastest Car Race Time x 0.30)) x (Fastest Car Race Time x 1.30 Team s Race Time) State Final Race Points = 75 + (120 / (Fastest Car Race Time x 0.20)) x (Fastest Car Race Time x 1.20 Team s Race Time) National Final Race Points = 75 + (120 / (Fastest Car Race Time x 0.15)) x (Fastest Car Race Time x 1.15 Team s Race Time) The minimum score awarded for a team completing the race is 75 marks and requires 7 legal runs. The minimum score awarded for a team starting but failing to complete the race is 30 marks plus 2 marks for each lap completed up to a maximum of 6 laps. Teams not starting the race (DNS) will receive 0 points. Cadet Class Regional Final Race Points = 20 + (45 / (Fastest Car Race Time x 0.30)) x (Fastest Car Race Time x 1.30 Team s Race Time) State Final Race Points = 20 + (45 / (Fastest Car Race Time x 0.20)) x (Fastest Car Race Time x 1.20 Team s Race Time) 18 P a g e

19 The minimum score awarded for a team completing the race is 20 marks and requires 3 legal runs. The minimum score awarded for a team starting but failing to complete the race is 10 marks plus 2 marks for each lap completed up to a maximum of 2 laps. Teams not starting the race (DNS) will receive 0 points. 2. KNOCK OUT REACTION LAUNCH RACING Some events MAY include knock-out reaction launch racing for Professional and Development Class Teams. The knockout draw is seeded based on team rankings from the reaction launch racing section (qualifying). An example draw for a field of 16 teams is shown. Sample Knockout Draw for a field of 16 Round of 16 Quarter Final Semi Final Final Winner Rank Each head to head pairing of teams is considered a match and the number of matches required to determine the winner is one less than the number of teams. With each car raced once in each lane against their opponent, the winner of a match is determined by the fastest reaction launch total time (gross time) from either run. If in both runs, both teams record DNFs, the better ranked team from qualifying will progress to the next round. Final Position in Knock-out (or Reaction Launch Racing Ranking) Winner Knock-out Champion (1 st ) Knocked out in Final (2 nd ) Knocked out in Semi-Final (3 rd or 4 th ) Knocked-out in Quarter Final (5th to 8 th place) Knocked out in a preliminary round (9 th to last place) Teams excluded from Knock-out racing Marks Awarded 30 marks 27 marks 24 marks each 18 marks each 12 marks each 0 marks The marks to be awarded from actual Knock-out racing outcomes or direct rankings from the reaction launch racing are shown in the following table. Where knock-out races are not specifically conducted due to time constraints, then the knock-out marks will be awarded based directly upon the reaction launch run time rankings. 19 P a g e

21 16. APPENDICES 1. DEVELOPMENT CLASS PIT DISPLAYS Rule 2o This area to remain void The intent of this rule is to reduce the cost and complexity for teams participating in the development class. At State & National Finals, REA will supply (where possible) an expo type booth with nominal external dimensions of 2000mm (L) x 1000mm (W) x 2400mm (H). Note that dimensions do vary between booth suppliers and REA will advise teams of exact external and internal booth dimensions 3 months prior to the event. Within these booths, Development Class team will be permitted to display only upon the backboard of the booth (Face C), the top (Face B) and front (Face A) of a trestle table provided by REA. Generally trestle table dimensions are 1800mm (L) x 750m (W) x 750mm (H), however these also differ from one supplier to another and teams will be advised of exact dimensions closer to the event. Teams are permitted to: 1. Extend the supplied trestle table top area (Face B) to a size equivalent to a maximum of 2000mm (L) x 900mm (W) as shown in the figure above using a false top. The thickness of this false top is not to exceed 20mm. Remember that internal width dimensions MAY be slighter smaller than 2000mm. 2. Substitute their own Face A & B structure to a maximum size of 2000mm (L) x 900mm (W) x 750mm (H) as shown in the figure above. 3. Use table cloths to cover tables and/or the false top. These are NOT supplied by REA. Faces A & B MUST be essentially planes and teams can only display upon these planes and not within the volume behind and below these faces or the vertical areas at the end of the table (shown as open in the diagram). However teams can use this space for storage and are permitted to inset TV monitors/screens or similar into Face B so long as what is being displayed & judged sits on or above Face B. Teams cannot use the sides of the booth (if booths are supplied at a competition with sides) and you cannot create your own side panels. All display items MUST be contained with the maximum width allowed for Face B (900mm) and cannot protrude beyond this. Platform/large structures cannot be placed upon Face B or attached to Face C. The height of any item displayed upon Face B including the structure upon which it sits, cannot be greater than 50cm in total. This excludes TV monitors and Portfolios which MUST sit directly on Face B and not be mounted within tower-like structures. 21 P a g e
